Hi all, The following was recently posted to stable and got only a me-too response from Igor Karpov <jc@minjust.gov.ua> who had posted his complaint to hardware. I read the post by taliesin@nvg.ntnu.no dated Nov. 24 and Chuck Swiger's reponse. All I've got to say on that is throwing money at this machine got me into this mess. I have a problem since adding a second hard drive to the 68-pin LVD/SE cable on an Adaptec 29160. The machine has two PPro 200 cpus, 384MB ram, Linksys lne100tx NIC, generic PCI USB card, Elsa Synergy II-32 PCI video card, Adaptec 1510 ISA SCSI controller (for a scanner) and SoundBlaster Vibra16 ISA card. There are two drives on the LVD/SE cable and neither is terminated as the cable is terminated. There is a SCSI CDRW on the 50-pin SE connector and a 9.2GB drive on the 68-pin SE connector. Both are terminated. Many months before, FreeBSD 4.0 was installed on the 18Gb drive and upgraded to then stable 4.4. When I tried booting 4.4 from the HD after adding the second LVD drive, parity errors ran up the screen and the machine automatically rebooted. Trying the 4.0 CD produced the same parity errors and a stall. Removing _all_ drives and cables but drive 0, the 18GB drive containing the earlier FreeBSD didn't work. There are now no circumstances that allow FreeBSD to install on that drive. Booting the 4.7 CD didn't work, but allowed getting debug output. All unnecessary cards were removed from the machine, leaving just the Adaptec and video card in hopes that something would improve, but it didn't. The Adaptec 29160 has the latest BIOS, V3.1, but this issue started with BIOS V2.57.2. Before adding the drive, there was one device per cable. 4.0 and 4.4 ran fine from the 18GB SCSI 160 drive. Here's the debug output (hand copied on another machine, please excuse typos) from vtty2 when 4.7R CD was booted to install on the new drive. There was nothing interesting from the generic kernel DMESG, it found the controller but was to much to copy and I couldn't get it all: DEBUG: ioctl(3, TIOCCONS, NULL) = 0 (success) DEBUG: Loading module if_wi.ko (Lucent WaveLAN/IEEE 8082.11 PCMCIA card) (da2:ahc0:0:2:0): parity error detected in Data-in phase.

These drives and adapter work in all configurations tried with MSDOS, Windows NT, and 2000 using supplied drivers from Adaptec and no drive parity or other drive errors were detected. At this point, I believe this to be a software problem. Any help or constructive ideas are appreciated.
